Pyrazinamide is an approved oral anti-tuberculosis drug used in combination regimens. It is used to prevent and to treat tuberculosis.

Side-effects include hepatitis, gastrointestinal upsets, rash and gout.

Pyrazinamide should not be prescribed to people who have a history of liver impairment. The risk of severe liver damage in HIV-negative patients has led United States drug regulation authorities to recommend that the combination of pyrazinamide and rifampicin (Rifadin / Rimactane) should not be offered to patients. However, the risk of liver damage may be lower in people infected with HIV.1

Pyrazinamide does not interact with any currently available protease inhibitors or non-nucleoside reverse transcriptase inhibitors (NNRTIs).

Patients taking pyrazinamide should drink plenty of fluids.

Pyrazinamide is manufactured by Merck Sharp & Dohme Ltd under the trade name Zinamide.

Community Consensus Statement on Access to HIV Treatment and its Use for Prevention

Together, we can make it happen

We can end HIV soon if people have equal access to HIV drugs as treatment and as PrEP, and have free choice over whether to take them.

Launched today, the Community Consensus Statement is a basic set of principles aimed at making sure that happens.

The Community Consensus Statement is a joint initiative of AVAC, EATG, MSMGF, GNP+, HIV i-Base, the International HIV/AIDS Alliance, ITPC and NAM/aidsmap
